The effect of the aqueous extracts of
Catharanthus roseus
and chlorpropamide (Diabenese) on the levels of serum cholesterol, total protein, lipid peroxidation, blood glucose and liver enzymes were compared in alloxan-induced diabetic rats. Four groups namely A, B, C and D comprising of nine rats each were used. A and B were administered with chlorpropamide and
C. roseus extracts respectively, while C and D served as diabetic and non-diabetic controls respectively. The results showed comparatively significant reductions (P≤ 0.05) in the levels of glucose, protein, cholesterol, lipid peroxidation and liver enzymes in the groups administered
C. roseus extracts and chlorpropamide relative to the controls. The reductions were higher in the groups treated with
C. roseus extract than in the groups treated with diabenese.
